PLANUREX 3 Standard Series

FLENDER’s Gear Unit for Aerator is a specialized vertical helical/bevel-helical gear unit tailored for wastewater treatment aeration systems, serving as a core power transmission component to ensure efficient and stable operation of aerators. Designed with wastewater treatment scenarios in mind, it effectively adapts to the humid, corrosive working environment of sewage treatment plants, with structural optimization to meet the unique operational demands of aeration equipment.

The gear unit covers 10 size specifications, with a nominal torque range of 10.5-173kNm and a transmission ratio of 6.3-112, enabling precise matching with different aerator models and aeration capacity requirements. Adopting a high-integrity oil-tight sealing structure, it effectively prevents lubricating oil leakage and the intrusion of moisture, sewage and impurities, avoiding gear corrosion and wear, thus extending the service life of the unit.

It is specially engineered to resist axial and lateral loads generated during aerator operation, with reinforced bearing assemblies that enhance load-bearing capacity and operational stability. The integration with Siemens Integrated Drive Systems (IDS) realizes seamless compatibility with motors, couplings and intelligent control modules, facilitating centralized monitoring and efficient operation management.

With optimized gear tooth design and precision machining, the unit achieves low-noise operation, reducing environmental noise pollution in sewage treatment plants. It is widely applicable to various aeration processes such as surface aeration and deep aeration, ensuring reliable power output for aerators to improve water oxygenation efficiency, and plays a key role in promoting the stability of wastewater treatment systems.
